James R. Barlow dea8fcfb5b Optimize page splitting by multiprocessing 
Previously page splitting occurred in a single process because it was
not believed to affect performance much. It turned out to be an expensive
operation.

It now scales better with large page sizes although this has a negative
effect on small files.

Overall time changes as follows:

7 page file, 9.02s -> 9.56s
731 page file, 213s -> 97s

WITH --tesseract-timeout 0 --output-type pdf --skip-text

i.e. you don't get a 2.2x speed gain when OCR is available.

Tucker Barbour 9fd9c7a51f Scale BoundingBox and Text elements to account for additional space. 
Here we are manually scaling the pt width used for the BoundingBox and
the Text element when manually adding whitespace to account for
limitations of the PDF.js viewer. This fixes an initial regression
noticed when selecting text elements in Chrome and PDFium. The width
of the Text element and BoundBox had not been adjusted for the
additional whitespace so the highlighting was offset slightly.

Charles Forcey 422e619978 Add a note to the documentation about interword-spaces 2018-03-01 13:15:03 -05:00
Tucker BarbourandCharles Forcey e6e34251c6 Add option to explicitly add interword spaces to HOCR pdf-renderer 
This commit includes an optional work around for limitations of the
PDF.js viewer described in
https://github.com/jbarlow83/OCRmyPDF/issues/133. Here is explicitly
add an addition space to text elements before drawing them on the PDF
canvas when using the HOCR renderer. This option does not apply to
other pdf renderers in OCRmyPDF and is turned off by default.
